List of explorers

The following is a list of explorers. Their common names, countries of origin (modern and former), centuries when they were active and main areas of exploration are listed below.

Leif Erikson was a famous Norse explorer who is credited for being the first European to set foot on American soil (c. 1000).

Marco Polo was an Italian explorer who traveled to the far east and back to his hometown Venice in the matter of 24 years. He is noted for making detailed chronicles of his travels (1271-1295).

Zheng He was a Chinese explorer who sailed along the Southeast Asian, South Asian, Western Asian, and East African coasts along with his fleet of incredibly large ships and several hundred men (1405-1433).

Leif Erikson
–
Leif Erikson or Leif Ericson was an Icelandic explorer and the first known European to have discovered North America, before Christopher Columbus. According to the Sagas of Icelanders, he established a Norse settlement at Vinland, later archaeological evidence suggests that Vinland may have been the areas around the Gulf of St. Lawrence and that the LAnse aux Meadows site was a ship repair station. Leif was the son of Erik the Red, the founder of the first Norse settlement in Greenland and he was likely born in Iceland, and grew up in the family estate Brattahlíð in the Eastern Settlement in Greenland. Leif had two sons, Thorgils, born to noblewoman Thorgunna in the Hebrides, and Thorkell. Leif was the son of Erik the Red and his wife Þjóðhildur, and the grandson of Thorvaldr Ásvaldsson, and distant relative of Naddodd and he was a Viking in the early days. His year of birth is most often given as c.970 or c, Leif had two brothers, whose names were Thorsteinn and Thorvaldr, and a sister, Freydís. Thorvald Asvaldsson was banished from Norway for manslaughter and went into exile in Iceland accompanied by young Erik, when Erik was himself banished from Iceland, he travelled further west to an area he named Greenland, where he established the first permanent settlement in 986. Tyrker, one of Eriks thralls, had been trusted to keep in charge of Eriks children. Leif and his crew travelled from Greenland to Norway in 999 AD, blown off course to the Hebrides and staying for much of the summer, he arrived in Norway and became a hirdman of King Olaf Tryggvason. He also converted to Christianity and was given the mission of introducing the religion to Greenland, the Saga of Erik the Red and the Saga of the Greenlanders, both thought to have been written around 1200, contain different accounts of the voyages to Vinland. The two only known strictly historical mentions of Vinland are found in the work of Adam of Bremen c.1075 and in the Book of Icelanders compiled c.1122 by Ari the Wise. According to the Saga of Erik the Red, Leif apparently saw Vinland for the first time after being blown off course on his way to introduce Christianity to Greenland, Bjarni reportedly never made landfall there, however. Later, when travelling from Norway to Greenland, Leif was also blown off course, to a land that he did not expect to see and he next rescued two men who were shipwrecked in this country and went back to Greenland. Leif then approached Bjarni, purchased his ship, gathered a crew of thirty-five men and his father Erik was set to join him but dropped out after he fell from his horse on his way to set sail, an incident he interpreted as a bad omen. Leif followed Bjarnis route in reverse and landed first in a rocky, after venturing further by sea, he landed the second time in a forested place he named Markland. Finally, after two days at sea, he landed in a verdant area with a mild climate. As winter approached, he decided to encamp there and broke his party into two groups - one to remain at camp and the other to explore the country, during one of these explorations, Tyrker discovered that the land was full of vines and grapes. Leif therefore named the land Vinland, there, he and his crew built a small settlement, which was called Leifsbúðir by later visitors from Greenland

2.
Americas
–
The Americas, also collectively called America, encompass the totality of the continents of North America and South America. Together they make up most of the land in Earths western hemisphere, along with their associated islands, they cover 8% of Earths total surface area and 28. 4% of its land area. The topography is dominated by the American Cordillera, a chain of mountains that runs the length of the west coast. The flatter eastern side of the Americas is dominated by river basins, such as the Amazon, St. Lawrence River / Great Lakes basin, Mississippi. Humans first settled the Americas from Asia between 42,000 and 17,000 years ago, a second migration of Na-Dene speakers followed later from Asia. The subsequent migration of the Inuit into the neoarctic around 3500 BCE completed what is regarded as the settlement by the indigenous peoples of the Americas. The first known European settlement in the Americas was by the Norse explorer Leif Ericson, however, the colonization never became permanent and was later abandoned. The voyages of Christopher Columbus from 1492 to 1502 resulted in permanent contact with European powers, diseases introduced from Europe and Africa devastated the indigenous peoples, and the European powers colonized the Americas. Mass emigration from Europe, including numbers of indentured servants. Decolonization of the Americas began with the American Revolution in 1776, the population is over 1 billion, with over 65% of them living in one of the three most populous countries. As of the beginning of the 2010s, the most populous urban agglomerations are Mexico City, New York, Sao Paulo, Los Angeles, Buenos Aires and Rio de Janeiro, all of them megacities. The name America was first recorded in 1507 in the Cosmographiae Introductio, apparently written by Matthias Ringmann and it first applied to both North and South America by Gerardus Mercator in 1538. Amerigen means land of Amerigo and derives from Amerigo and gen, America accorded with the feminine names of Asia, Africa, and Europa. When conceived as a continent, the form is generally the continent of America in the singular. However, without a context, singular America in English commonly refers to the United States of America. In some countries of the world, America is considered a continent encompassing the North America and South America subcontinents, the first inhabitants migrated into the Americas from Asia. Habitation sites are known in Alaska and the Yukon from at least 20,000 years ago, beyond that, the specifics of the Paleo-Indian migration to and throughout the Americas, including the dates and routes traveled, are subject to ongoing research and discussion. Widespread habitation of the Americas occurred during the glacial maximum

Marco Polo
–
He learned the mercantile trade from his father and uncle, Niccolò and Maffeo, who travelled through Asia and met Kublai Khan. In 1269, they returned to Venice to meet Marco for the first time, the three of them embarked on an epic journey to Asia, returning after 24 years to find Venice at war with Genoa, Marco was imprisoned and dictated his stories to a cellmate. He was released in 1299, became a merchant, married. He died in 1324 and was buried in the church of San Lorenzo in Venice, Marco Polo was not the first European to reach China, but he was the first to leave a detailed chronicle of his experience. This book inspired Christopher Columbus and many other travellers, there is a substantial literature based on Polos writings, he also influenced European cartography, leading to the introduction of the Fra Mauro map. Marco Polo was born in 1254 in Venice Republic and his exact date and place of birth are archivally unknown. Some historians mentioned that he was born on September 15 but that date is not endorsed by mainstream scholarship, Marco Polos birthplace is generally considered Venice, but also varies between Constantinople, and the island of Korčula. There is dispute as to whether the Polo family is of Venetian origin, the first recorded Polo is Venetian Domenico Polo who was mentioned in 971 regarding the prohibition of trade with the Arabs. Later other Polos were also mentioned in the service of the realm, whether they were related with the family of Marco Polo is uncertain, but this could indicate that his ancestors travelled between Venice and Dalmatia. Some of the first indications of where his family originated and were resident come from Venetian documents and manuscripts. Some scholars argued that this account could go along with the note from Il Milione that his father and uncle, Niccolò and Maffeo Polo, the non-Venetian i. e. Sanuto also mentioned a captain from Korčula, Antonio di Polo. Moule cited two early 17th century Venetian manuscripts questi ueneno de dalmatia, Polo questi uene de Dalmatia, scholars etymologically argued that his family name derives from Latin Paulus, the name of a certain bird species, or like Albert tSerstevens considered - from Eastern origin. However, the habitat of the shorebird is non-existent on Korčula, the surname Polo seems related with other widespread Dalmatian surnames. The lack of evidence makes the Korčula theory as a specific birthplace strongly disputed, in 1168, his great-uncle, Marco Polo, borrowed money and commanded a ship in Constantinople. His grandfather, Andrea Polo of the parish of San Felice, had three sons, Maffeo, yet another Marco, and the travellers father Niccolò and this genealogy, described by Ramusio, is not universally accepted as there is no additional evidence to support it. His father, Niccolò Polo, a merchant, traded with the Near East, becoming wealthy, Niccolò and his brother Maffeo set off on a trading voyage before Marcos birth. In 1260, Niccolò and Maffeo, while residing in Constantinople, then the capital of the Latin Empire, foresaw a political change, they liquidated their assets into jewels and moved away. According to The Travels of Marco Polo, they passed through much of Asia, and met with Kublai Khan and their decision to leave Constantinople proved timely

Venice
–
Venice is a city in northeastern Italy and the capital of the Veneto region. It is situated across a group of 118 small islands that are separated by canals and these are located in the shallow Venetian Lagoon, an enclosed bay that lies between the mouths of the Po and the Piave Rivers. Parts of Venice are renowned for the beauty of their settings, their architecture, the lagoon and a part of the city are listed as a World Heritage Site. In 2014,264,579 people resided in Comune di Venezia, together with Padua and Treviso, the city is included in the Padua-Treviso-Venice Metropolitan Area, with a total population of 2.6 million. PATREVE is a metropolitan area without any degree of autonomy. The name is derived from the ancient Veneti people who inhabited the region by the 10th century BC, the city was historically the capital of the Republic of Venice. Venice has been known as the La Dominante, Serenissima, Queen of the Adriatic, City of Water, City of Masks, City of Bridges, The Floating City, and City of Canals. The City State of Venice is considered to have been the first real international financial center which gradually emerged from the 9th century to its peak in the 14th century and this made Venice a wealthy city throughout most of its history. It is also known for its several important artistic movements, especially the Renaissance period, Venice has played an important role in the history of symphonic and operatic music, and it is the birthplace of Antonio Vivaldi. Venice has been ranked the most beautiful city in the world as of 2016, the name Venetia, however, derives from the Roman name for the people known as the Veneti, and called by the Greeks Eneti. The meaning of the word is uncertain, although there are other Indo-European tribes with similar-sounding names, such as the Celtic Veneti, Baltic Veneti, and the Slavic Wends. Linguists suggest that the name is based on an Indo-European root *wen, so that *wenetoi would mean beloved, lovable, a connection with the Latin word venetus, meaning the color sea-blue, is also possible. The alternative obsolete form is Vinegia, some late Roman sources reveal the existence of fishermen on the islands in the original marshy lagoons. They were referred to as incolae lacunae, the traditional founding is identified with the dedication of the first church, that of San Giacomo on the islet of Rialto — said to have taken place at the stroke of noon on 25 March 421. Beginning as early as AD166 to 168, the Quadi and Marcomanni destroyed the center in the area. The Roman defences were again overthrown in the early 5th century by the Visigoths and, some 50 years later, New ports were built, including those at Malamocco and Torcello in the Venetian lagoon. The tribuni maiores, the earliest central standing governing committee of the islands in the Lagoon, the traditional first doge of Venice, Paolo Lucio Anafesto, was actually Exarch Paul, and his successor, Marcello Tegalliano, was Pauls magister militum. In 726 the soldiers and citizens of the Exarchate rose in a rebellion over the controversy at the urging of Pope Gregory II

Zheng He
–
Zheng He, formerly romanized as Cheng Ho, was a Hui Chinese mariner, explorer, diplomat, and fleet admiral during Chinas early Ming dynasty. Born Ma He, Zheng commanded expeditionary voyages to Southeast Asia, South Asia, Western Asia and his larger ships stretched 120 meters in length. These carried hundreds of sailors on four tiers of decks, as a favorite of the Yongle Emperor, whose usurpation he assisted, Zheng He rose to the top of the imperial hierarchy and served as commander of the southern capital Nanjing. A trilingual stele left by the navigator was discovered on the island of Sri Lanka shortly thereafter, Zheng He was the second son of a family from Kunyang, Yunnan. He was originally born with the name Ma He and he had four sisters and one older brother. Zheng He was born into a Muslim family, however, his religious beliefs became all-embracing and eclectic in his adulthood. He was a great-great-great-grandson of Sayyid Ajjal Shams al-Din Omar, a Persian who served in the administration of the Mongol Empire and was the governor of Yunnan during the early Yuan dynasty and his great-grandfather was named Bayan and may have been stationed at a Mongol garrison in Yunnan. His grandfather carried the title hajji and his father had the surname Ma and the title hajji. The title suggests that they had made the pilgrimage to Mecca and it also suggests that Zheng He may have had Mongol and Arab ancestry and that he could speak Arabic. In the autumn of 1381, a Ming army invaded and conquered Yunnan, in 1381, Ma Hajji died in the fighting between the Ming armies and Mongol forces. Dreyer states that Zheng Hes father died at age 39 while resisting the Ming conquest, Levathes states Zheng Hes father died at age 37, but it is unclear if he was helping the Mongol army or just caught in the onslaught of battle. Wenming, the oldest son, buried their father outside of Kunming, in his capacity as Admiral, Zheng He had an epitaph engraved in honor of his father, composed by the Minister of Rites Li Zhigang on the Duanwu Festival of the 3rd year in the Yongle era. Zheng He was captured by the Ming armies at Yunnan in 1381, General Fu Youde saw Zheng He on a road and approached him in order to inquire about the location of the Mongol pretender. Zheng He responded defiantly by saying that the Mongol pretender had jumped into a lake, afterwards, the general took him prisoner. The young Zheng He was soon castrated before being placed in servitude of the Prince of Yan, however, Levathes has stated that he was castrated in 1385. He was sent to serve in the household of Zhu Di, the Prince of Yan and he was 10 years old when he entered into the service of the Prince of Yan. Zhu Di was eleven years older than Zheng He, since 1380, the prince had been governing Beiping, which was located near the northern frontier where the hostile Mongol tribes were situated. Zheng He would spend his life as a soldier on the northern frontier

Portugal
–
Portugal, officially the Portuguese Republic, is a country on the Iberian Peninsula in Southwestern Europe. It is the westernmost country of mainland Europe, to the west and south it is bordered by the Atlantic Ocean and to the east and north by Spain. The Portugal–Spain border is 1,214 kilometres long and considered the longest uninterrupted border within the European Union, the republic also includes the Atlantic archipelagos of the Azores and Madeira, both autonomous regions with their own regional governments. The territory of modern Portugal has been settled, invaded. The Pre-Celts, Celts, Carthaginians and the Romans were followed by the invasions of the Visigothic, in 711 the Iberian Peninsula was invaded by the Moors, making Portugal part of Muslim Al Andalus. Portugal was born as result of the Christian Reconquista, and in 1139, Afonso Henriques was proclaimed King of Portugal, in the 15th and 16th centuries, Portugal established the first global empire, becoming one of the worlds major economic, political and military powers. Portugal monopolized the trade during this time, and the Portuguese Empire expanded with military campaigns led in Asia. After the 1910 revolution deposed the monarchy, the democratic but unstable Portuguese First Republic was established, democracy was restored after the Portuguese Colonial War and the Carnation Revolution in 1974. Shortly after, independence was granted to almost all its overseas territories, Portugal has left a profound cultural and architectural influence across the globe and a legacy of over 250 million Portuguese speakers today. Portugal is a country with a high-income advanced economy and a high living standard. It is the 5th most peaceful country in the world, maintaining a unitary semi-presidential republican form of government and it has the 18th highest Social Progress in the world, putting it ahead of other Western European countries like France, Spain and Italy. Portugal is a pioneer when it comes to drug decriminalization, as the nation decriminalized the possession of all drugs for use in 2001. The early history of Portugal is shared with the rest of the Iberian Peninsula located in South Western Europe, the name of Portugal derives from the joined Romano-Celtic name Portus Cale. Other influences include some 5th-century vestiges of Alan settlements, which were found in Alenquer, Coimbra, the region of present-day Portugal was inhabited by Neanderthals and then by Homo sapiens, who roamed the border-less region of the northern Iberian peninsula. These were subsistence societies that, although they did not establish prosperous settlements, neolithic Portugal experimented with domestication of herding animals, the raising of some cereal crops and fluvial or marine fishing. Chief among these tribes were the Calaicians or Gallaeci of Northern Portugal, the Lusitanians of central Portugal, the Celtici of Alentejo, a few small, semi-permanent, commercial coastal settlements were also founded in the Algarve region by Phoenicians-Carthaginians. Romans first invaded the Iberian Peninsula in 219 BC, during the last days of Julius Caesar, almost the entire peninsula had been annexed to the Roman Republic. The Carthaginians, Romes adversary in the Punic Wars, were expelled from their coastal colonies and it suffered a severe setback in 150 BC, when a rebellion began in the north

Congo River
–
The Congo River is a river in Africa. It is the second largest river in the world by discharge, the Congo-Chambeshi river has an overall length of 4,700 km, which makes it the ninth-longest river. Measured along the Lualaba, the Congo River has a length of 4,370 km. The Congo Basin has an area of about 4 million km2. The name River Congo originated from the Kingdom of Kongo which was located on the bank of the river. The kingdom in turn is named for the Bantu population, in the 17th century reported as Esikongo, South of the Kongo kingdom proper lay the similarly named Kakongo kingdom, mentioned in 1535. Abraham Ortelius in his map of 1564 labels as Manicongo the city at the mouth of the river. The tribal names in kongo possibly derive from a word for a gathering or tribal assembly. Little is known about the peoples of the inner Congo, but It is probable that the word Kongo itself implies a public gathering, the usual interpretations, admittedly unsatisfactory, make the mistake of being too concrete, for example, they may claim that Kongo comes from nkongo. The modern name of the Kongo people or Bakongo was introduced in the early 20th century, the name Zaire is from a Portuguese adaptation of a Kikongo word nzere, a truncation of nzadi o nzere. The Democratic Republic of the Congo and the Republic of the Congo are named after it, the state of Zaire during 1971–1997 was also named after the river, after its name in French and Portuguese. The Congos drainage basin covers 4,014,500 square kilometres, the Congos discharge at its mouth ranges from 23,000 to 75,000 cubic metres per second, with an average of 41,000 cubic metres per second. The river and its tributaries flow through the Congo Rainforest, the second largest rain forest area in the world, second only to the Amazon Rainforest in South America. Because its drainage basin includes both north and south of the equator, its flow is stable, as there is always at least one part of the river experiencing a rainy season. The Chambeshi River in Zambia is generally taken as the source of the Congo in line with the accepted practice worldwide of using the longest tributary, as with the Nile River. The Congo River Basin is one of the distinct physiographic sections of the larger Mid-African province, sorted in order from the mouth heading upstream. Lower Congo Downstream of Kinshasa, there are no important tributaries, luvua Luapula Chambeshi Although the Livingstone Falls prevent access from the sea, nearly the entire Congo above them is readily navigable in sections, especially between Kinshasa and Kisangani. Large river steamers worked the river until quite recently, the Congo River still is a lifeline in a land with few roads or railways

8.
Equator
–
The Equator usually refers to an imaginary line on the Earths surface equidistant from the North Pole and South Pole, dividing the Earth into the Northern Hemisphere and Southern Hemisphere. The Equator is about 40,075 kilometres long, some 78. 7% lies across water and 21. 3% over land, other planets and astronomical bodies have equators similarly defined. Generally, an equator is the intersection of the surface of a sphere with the plane that is perpendicular to the spheres axis of rotation. The latitude of the Earths equator is by definition 0° of arc, the equator is the only line of latitude which is also a great circle — that is, one whose plane passes through the center of the globe. The plane of Earths equator when projected outwards to the celestial sphere defines the celestial equator, in the cycle of Earths seasons, the plane of the equator passes through the Sun twice per year, at the March and September equinoxes. To an observer on the Earth, the Sun appears to travel North or South over the equator at these times, light rays from the center of the Sun are perpendicular to the surface of the Earth at the point of solar noon on the Equator. Locations on the Equator experience the quickest sunrises and sunsets because the sun moves nearly perpendicular to the horizon for most of the year. The Earth bulges slightly at the Equator, the diameter of the Earth is 12,750 kilometres. Because the Earth spins to the east, spacecraft must also launch to the east to take advantage of this Earth-boost of speed, seasons result from the yearly revolution of the Earth around the Sun and the tilt of the Earths axis relative to the plane of revolution. During the year the northern and southern hemispheres are inclined toward or away from the sun according to Earths position in its orbit, the hemisphere inclined toward the sun receives more sunlight and is in summer, while the other hemisphere receives less sun and is in winter. At the equinoxes, the Earths axis is not tilted toward the sun, instead it is perpendicular to the sun meaning that the day is about 12 hours long, as is the night, across the whole of the Earth. Near the Equator there is distinction between summer, winter, autumn, or spring. The temperatures are usually high year-round—with the exception of high mountains in South America, the temperature at the Equator can plummet during rainstorms. In many tropical regions people identify two seasons, the wet season and the dry season, but many places close to the Equator are on the oceans or rainy throughout the year, the seasons can vary depending on elevation and proximity to an ocean. The Equator lies mostly on the three largest oceans, the Pacific Ocean, the Atlantic Ocean, and the Indian Ocean. The highest point on the Equator is at the elevation of 4,690 metres, at 0°0′0″N 77°59′31″W and this is slightly above the snow line, and is the only place on the Equator where snow lies on the ground. At the Equator the snow line is around 1,000 metres lower than on Mount Everest, the Equator traverses the land of 11 countries, it also passes through two island nations, though without making a landfall in either. Starting at the Prime Meridian and heading eastwards, the Equator passes through, Despite its name, however, its island of Annobón is 155 km south of the Equator, and the rest of the country lies to the north

Christopher Columbus
–
Christopher Columbus was an Italian explorer, navigator, colonizer, and citizen of the Republic of Genoa. Under the auspices of the Catholic Monarchs of Spain, he completed four voyages across the Atlantic Ocean and those voyages and his efforts to establish permanent settlements on the island of Hispaniola initiated the European colonization of the New World. Western imperialism and economic competition were emerging among European kingdoms through the establishment of routes and colonies. During his first voyage in 1492, he reached the New World instead of arriving at Japan as he had intended, landing on an island in the Bahamas archipelago that he named San Salvador. Over the course of three voyages, he visited the Greater and Lesser Antilles, as well as the Caribbean coast of Venezuela and Central America. These voyages had, therefore, an impact in the historical development of the modern Western world. He spearheaded the transatlantic trade and has been accused by several historians of initiating the genocide of the Hispaniola natives. Columbus himself saw his accomplishments primarily in the light of spreading the Christian religion, Columbus never admitted that he had reached a continent previously unknown to Europeans, rather than the East Indies for which he had set course. He called the inhabitants of the lands that he visited indios, the name Christopher Columbus is the Anglicisation of the Latin Christophorus Columbus. His name in Italian is Cristoforo Colombo and, in Spanish and he was born before 31 October 1451 in the territory of the Republic of Genoa, though the exact location remains disputed. His father was Domenico Colombo, a wool weaver who worked both in Genoa and Savona and who also owned a cheese stand at which young Christopher worked as a helper. Bartolomeo, Giovanni Pellegrino, and Giacomo were his brothers, Bartolomeo worked in a cartography workshop in Lisbon for at least part of his adulthood. He also had a sister named Bianchinetta, Columbus never wrote in his native language, which is presumed to have been a Genoese variety of Ligurian. In one of his writings, he says he went to sea at the age of 10, in 1470, the Columbus family moved to Savona, where Domenico took over a tavern. In the same year, Christopher was on a Genoese ship hired in the service of René of Anjou to support his attempt to conquer the Kingdom of Naples. Some modern historians have argued that he was not from Genoa but, instead and these competing hypotheses have generally been discounted by mainstream scholars. In 1473, Columbus began his apprenticeship as business agent for the important Centurione, Di Negro, later, he allegedly made a trip to Chios, an Aegean island then ruled by Genoa. In May 1476, he took part in a convoy sent by Genoa to carry valuable cargo to northern Europe

Juan de la Cosa
–
De la Cosa played an important role in the first and second voyage of Christopher Columbus to the West Indies, since he was the owner and captain of the Santa María. In 1499, he served as the pilot in the expedition of Alonso de Ojeda to the coasts of South America. Upon his return to Andalusia, he drew his famous mappa mundi and soon returned to the Indies, in 1509, he began what would be his last expedition, again with Ojeda, to take possession of the coasts of modern Colombia. De la Cosa died in an confrontation with indigenous people before he could get possession of Urabá. Some 16th-century chroniclers called him the Biscayan, leading to confusion with another sailor called Juan Vizcaino, however, today they are known to be different people. His date of birth is unknown, but it is estimated between 1450 and 1460, nor is any information available from his childhood or adolescence. It is assumed that the man took part in sailing voyages around the Bay of Biscay and then towards the Canary Islands. The first solid references come from 1488, when Juan de la Cosa was in Portugal, at that time, navigator Bartolomeu Dias had just arrived in Lisbon, after having reached the Cape of Good Hope. The Catholic Monarchs may have sent de la Cosa to that city as a spy to obtain information and he managed to return to Castile before Portuguese officers captured him. Early in the 1490s, Juan de la Cosa was living in El Puerto de Santa María and it is believed that it was there that he established a business relationship with the Pinzón brothers. According to some historians he was born in 1460 at Sta, maria del Puerto, in Cantabria, Spain. From early childhood he spent time on the water, from the waters of his native country, which he knew thoroughly, he soon ventured on to the coast of Western Africa, which was at that time the goal of many Spanish expeditions. The first reliable references place him in Portugal in 1488, meeting the explorer Bartolomeu Dias who had just sailed around the Cape of Good Hope, Juan de la Cosa sailed with Christopher Columbus on his first three voyages to the New World. He owned and was master of the Santa María, flagship of Columbuss first voyage in 1492, the vessel shipwrecked that year on the night of 24–25 December off the present-day site of Cap-Haïtien, Haiti. On Columbuss second voyage, in 1493, de la Cosa was mariner and cartographer on the ship Colina, on Columbus third voyage, in 1498, de la Cosa was on the ship La Niña. Some historians believe de la Cosa did not participate in this voyage, in 1494 de la Cosa received compensation from the Spanish monarchs for the sinking of his ship on his first voyage. He was awarded the right to transport docientos cahíces de trigo from Andalucia to Biscay, at the same time they explored the coast from Essequibo River to Cape Vela. In spite of not receiving much remuneration, De la Cosa had benefited considerably, having mapped in detail the coast of the region he explored, information he would use to create his famous map

Amerigo Vespucci
–
Colloquially referred to as the New World, this second super continent came to be termed Americas, deriving its name from Americus, the Latin version of Vespuccis first name. Amerigo Vespucci was born and raised in Florence on the Italian Peninsula and he was the third son of Ser Nastagio Vespucci, a Florentine notary, and Lisabetta Mini. The father of Ser Nastagio Vespucci had the name Amerigo Vespucci also, Amerigo Vespucci was educated by his uncle, Fra Giorgio Antonio Vespucci, a Dominican friar of the monastery of San Marco in Florence. Vespucci acquired the favor and protection of Lorenzo di Pierfrancesco de Medici who became the head of the business after the elder Lorenzos death in 1492, just around this time, Vespucci was engaged as the executor of Giannotto Berardi, an Italian merchant who had recently died in Seville. Vespucci organized the fulfillment of Berardis outstanding contract with the Castilian crown to provide twelve vessels for the Indies, after these were delivered, Vespucci continued as a provision contractor for Indies expeditions, and is known to have secured beef supplies for at least one of Columbus voyages. At the invitation of king Manuel I of Portugal, Vespucci participated as observer in several voyages that explored the east coast of South America between 1499 and 1502. On the first of these voyages he was aboard the ship that discovered that South America extended much further south than previously thought, the expeditions became widely known in Europe after two accounts attributed to Vespucci were published between 1502 and 1504. In 1507, Martin Waldseemüller produced a map on which he named the new continent America after the feminine Latin version of Vespuccis first name. In an accompanying book, Waldseemüller published one of the Vespucci accounts, in 1508, the position of chief of navigation of Spain was created for Vespucci, with the responsibility of planning navigation for voyages to the Indies. Two letters attributed to Vespucci were published during his lifetime, mundus Novus was a Latin translation of a lost Italian letter sent from Lisbon to Lorenzo di Pierfrancesco de Medici. It describes a voyage to South America in 1501–1502, mundus Novus was published in late 1502 or early 1503 and soon reprinted and distributed in numerous European countries. Lettera di Amerigo Vespucci delle isole nuovamente trovate in quattro suoi viaggi, printed in 1504 or 1505, it claimed to be an account of four voyages to the Americas made by Vespucci between 1497 and 1504. A Latin translation was published by the German Martin Waldseemüller in 1507 in Cosmographiae Introductio, Vespucci even developed a rudimentary, but fairly accurate method of determining longitude. In the 18th century, three unpublished familiar letters from Vespucci to Lorenzo de Medici were rediscovered, one describes a voyage made in 1499–1500 which corresponds with the second of the four voyages. Another was written from Cape Verde in 1501 in the part of the third of the four voyages. The third letter was sent from Lisbon after the completion of that voyage, some have suggested that Vespucci, in the two letters published in his lifetime, was exaggerating his role and constructed deliberate fabrications. However, many now believe that the two letters were not written by him but were fabrications by others based in part on genuine letters by Vespucci. It was the publication and widespread circulation of the letters that might have led Waldseemüller to name the new continent America on his map of 1507 in Lorraine
